Abstract: A mixing valve assembly includes a valve housing defining an interior, a cold inlet along a first axis, a hot inlet, and a mixed outlet. A metering ball within the interior rotates about the first axis. The metering ball has an outer shell defining: a cold port aligned with the cold inlet; a hot port selectively aligned with the hot inlet; a cold outlet connected to the cold port; and a hot outlet connected to the hot port. Rotation of the metering ball aligns the hot port with the hot inlet, the cold outlet with the mixed outlet, and the hot outlet with the mixed outlet to varying degrees. The metering ball has a central flowpath for hot water and a radially outward flowpath for cold water.
